' rnivcn I fififiiiiibii hi aviuiy, a1, sakes-. 1 nagsaassz a I This inventionrelates to certainnovel improvements in hand punches, and has for its principal object the provision of an improved construction of this character which will be highly efficient in use and economical in manufacture.

It is an object of this invention to provide rpintle 27,*atthe sides of the arms 24 and 25,

an improved hand punch for forming characters in metal. a r H Another object of the invention resides in providing a hand punch for forming identifying characters in metal vehicle license plates. i

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangementofparts to be hereinafter described and claimed.

The invention will be best understood by; reference to the accompanying drawings showing the preferred form of construction, and in which: p 7

Fig. 1 is a top plan view of a preferred construction of the invention;

Fig. 2 is a side elevational view on line 22 in Fig. 1; and

Fig. 3 is a sectional view on line 3-3 Fig. 1. i

r In the drawings, which illustrate a prac tical and preferred embodiment ofthe invention, indicated generally at and 11 are opposed jaws which are pivotally connected by the pintle 13, and urged apart by a spring 14 secured therebetween. i

The jaw 10 is bifurcated to provide spaced arms 16 and 17, through'apertures in which is extended a bolt 18 having a threaded end on which is a nut 19 that secures the bolt in position. A rotative male drum punch 20 is mounted on the bolt or pintle 18, between washers 23, and this drum is provided with raised letters 21, which are,in the present instance, arranged to form the names of various automobiles for reasons hereinafter mentioned. 7 r

Likewise formed by a bifurcation of the which are aligned with but spaced from the arms 16 and 17. Provided in the arms 24 and 25 are slots 26 through which is extended 'eachfother. Sincetheears 3570f jaw 11 -arel pivotally mounted on pintle.13,,.pressure handpunch. e 1;

Ina typical use of theinvention, the work,

whichmayqbe-arnetal automotive vehicle license; plate, 1 may be disposed between the '7 f drums 2O and 30, the drums rotated to align corresponding characters thereon, and the jaws 1,0 and 11 may then bepressed toward eXerted-=,0nithe .jaws 10 and 1140' force them together, 7 will: cause the .pinions 34, formed atzth'e 'ends of ears 35, to pivot the 1 racks 32 about their mountings 37 and the pintle 27 and-drum 30 will thus-be forced '30 against -the metal plate. disposed between drum punches Y20 and 31, fthe pintle 27mov.
